l pieces 76 and 77. On sliding piece 77 is hung pawl 78, and it is also provided with the spring dog 7 9; held in engagement with rack 73 by its spring and provided with a thumb piece for releasing it therefrom, so that said sliding iecemay be locked to the rack 7 3 at any esired point; 90 90 are stop pins for limiting the stroke of the swinging pawl 7S sliding piece 76 is also provided with a similar spring pawil 9, spring and thumb piece, wherebyltV-Ymay be locked in any desired positionfgrid carries-swinging stop 81, limited in' its stroke by means of pin S3, engaging in `its slotted end whereby va slight movement is obtained preventing a sucden jar or rebounding thereof when it engages with 'abutment S8 on lever 80. .Said stop 81 is to engage with abutment 88 and limit the movement of 'the carriage'when it is moved back to the left.l Said lever SO is journaled at. 85, and-provided with two cam surfaces 8 6, 87, and-'abutment 88. Pawl 78 engages with ca m face 86, pressing the lever downwardly and ringing 'the bell, then travels over the straight face and engages with cam 87, lockinfr the key bars and immediately stopping the carriage by engagement with abutment 88, by means of the mechanism to be described.

. At its outer end lever 8O isconnected by eonneeting'bar 89 to one end of the bell lever 92, journaled tothe frame by screw 93, and carrying on its lower arm the pivoted dog 94, so adjusted that, as'c'onnecting arm is raised, it will engage with a pin 105 on the outer end of the bell-hammer lever 95, journaled at- 97, rock it against the force of the spring 96, and then release it, ringing the bell u; this is eiiect'ed by the engagement of the pawl 78 A To the lower arm of bell lever 92 is pivotally connected sliding lever 63, so, that when pawl` 78 engages with cam surface 87, connecting rod 89 is further raised, and pin 62 on sliding lever 63 is. moved forward to engage with the tail 64,

pivotally su ported onextension 65 at 66, and there he d in position by spring 71, limited Ain its movement by lug 91 which is integral with the tail 64. This extension is secured on rod 68 journaled in the frame. and carrying the locking levers 67, supporting locking rod 70 for engagement with key lever catches. 69, and held back by a weaker Spring 10N or New IOO To print more letters-after the key levers are locked andthe carriage is stopped, itis necessary. l-to draw sliding lever* 63 fiiarther so that cam 78:V 'can rideover it and drop l down on the other side; this is permitted by the arrangement of the tail 64, which snaps over the pin 62 into 'normal-position, and the lspring 102 throws locking' rod 7 0 out ofengagement With notches 69, unlocking. the keys and permitting one or more characters spring n restores the parts to their normal position. v

l do not limit myself tothe 'construction here described, as the mechanism and arrangement oi parts may be varied.
